        this.transportChannels = [];
        this.activeChannel = null;
    }
    
    // Establish multiple transport channels over different paths
    establishTransportChannels() {
        // Create cellular data channel
        let cellularChannel = new TransportChannel('cellular');
        this.transportChannels.push(cellularChannel);
        
        // Create WiFi channel
        let wifiChannel = new TransportChannel('wifi');
        this.transportChannels.push(wifiChannel);
        
        // Select best performing channel as active
        this.activeChannel = this.selectBestChannel();
    }
    
    // Handle network transition by switching transport channels
    handleNetworkChange(newNetworkType) {
        console.log(`Network changed to ${newNetworkType}`);
        
        // Find appropriate channel for new network condition
        let newChannel = this.transportChannels.find(c => c.type === newNetworkType);
        
        // Transfer session to new channel without dropping connection
        this.migrateSessionTo(newChannel);
        this.activeChannel = newChannel;
        
        console.log(`Session ${this.sessionID} migrated to ${newNetworkType} without disconnection`);
    }
}
